'msn-wasnma MACHINE.

To all whom it may concern Be it known that l. MARY E. MILLER, a citizen of the United States, residing at Granite Falls, in the county of Snohomish have invented new and useful Improvements in Dish- Washing Machines, of which the following is a -specification.

This invention relates to dish washing machines and has foran object, to provide a machine of this character which will include a revolving" vessel adapted to be mounted in a body of 'water whereby.

through centrifugal force water will be scattered through and against the articles so as to produce the maximum cleansing operation.

Another object of the, invention is to provide apparatus of this character that can 'be operated manually with the minimum ower.

A still further object of the invention is to provide apparatus which will include an "innerdish or article container and an outer water containing vessel, the'latter being removably associated with the former -where. by the container and the vessel can be thoro'ughly cleaned when desired.

Another object of the invention is to provide washing apparatus wherein the walls of the article container will have minimum contact with the walls of the water container and to arrange the bearing portions so as to eliminate undue friction between the parts and to efiectually sustain the weight .of the dish or article container- In the drawing forming a portion of this ap lication and in which Like letters of -re erence indicate similar parts in the several views :Figure 1 is a side view of the apparatus showing the driving and driven gears in intermeshing engagement. Fig. 2 is' a similar view showing the top and side bearing brackets adjusted so as to permit. of removal of the dish or article containing is a vertical section through vessel. Fig. 3 the machine. Fig. a is a horizontal section and Fig. 5 is a sectionthrough a slightl modified form, of'bearing bracket.

The dishwasher comprises an outer water containing vessel 1' and an inner dish or article containing vessel. 2, the latter being Specification of Letters Patent.

rotatably mounted in the former and being constructed whereby under centrifugal force the water will be compelled to circulate with considerable force in both vessels so as to positively subject the dishes or articles to be cleaned'to the full force of the circulating water. The outer water containing ves- 'sel 1 is preferably provided with a substantially inverted conical bottom 3 whose walls tom 3, being disposed in -'axial alinement with the driven shaft 8 and having a point' ed extremity 9 which is fitted in a step bearing 10 in the bottom of the article or dish containing vessel 2. The vessel 2 has its vertical walls spaced from the vertical walls of the vessel 1 while the bottom 11 of the vessel 2 is spaced shown. The vessel the driven shaft 8 secured as at 12 to the center of the bottom 11 and as illustrated the shaft 8 is provided with a pointed bearing end 13 whlch is disposed above the plane of the vessels 1 and 2 and which is revolubly eggs 6 are secured whereby the i from the bottom 3 as 2 has the lower end of' mounted in a bearing socket let in a bracket 15. The bracket 15 extends horizontally across the vessels 1 and 2, being hingedly connected at 15 to a vertical standard 17 which rises from one side of the vessel 1, while the opposite end of the bracket 15 rests upon a horizontal shoulder 18 of a standard 19 which also rises from one side of the vessel 1 and which is hinged thereto as at 20 whereby it may be swung down against one side of the vessel as shown in Fig. 2 of the drawings. A'latch bolt 22 upon the bracket 19 is removably engaged with a keeper 21 on the vessel 1. When the bolt is engaged with the keeper as. shown in Fig. 1 the said standard 19 is eifectually held against br'eakinglonQxe hinge 20. A ver-- tical extension 23 of the shoulder 18 has a keeper passage 24 therein which is designed to receive a sliding bolt 24 upon the bracket 15 whereby the latter is held against swinging movement.

The standard 19 is provided with a bearing 26 and as illustrated a driving shaft 27 is j ournaled therein and in the standard, the shaft being provided with a fixed driving gear wheel 28 which meshes with wheel 29 on the shaft 8 as shown in Fig. 1. The shaft 27 carries an operating crank handle 30 which maybe controlled manually whereby power transmitted to the shaft 27 will impart rotary movement to the article containing vessel 2. The bottom 11 of the receptacle 2 is provided with an annular series of openings 31 and agitating flanges or surfaces 32. The surfaces 32 are inclined in the direction of the bottom 3 of the receptacle 1 so that when the vessel 2 is revolved water in the vessel 1 will be agitated and circulated and deflected into the vessel 2. The vessel 2 is also provided with circumferential openings 33 and tangentially disposed agitating surfaces or flanges 33 which are designed to create a circulatory agitation of the water in the vessel 2.

From the construction of the machine de scribed it is evident that dishes or other articles when placed in the vessel 2 will be thoroughly subjected and treated to the circulating water with a resultant thorough cleansing of the articles. Incident to the construction of the bracket 15 and the standard 19 it is seen that when they are adjusted to the positions shown in Fig. 2 the vessels 1 and 2 may be separated from each other where they may be cleaned and maintained in a highly sanitary condition.

Bearing rollers 34 are secured to the lower corner of the vessel 2 and are adapted to travel across the adjacent inner walls of the bottom 3. The bottom 3 thereby forms a stop to limit the vertical adjustment of the vessel 2. To maintain the vessels 1 and 2 in proper spaced relation vertically and to eliminate undue friction .of the parts when the inner vessel is rotated I provide the said inner vessel near its upper end with radi* ally extending rollers 35 which are adapted to travel against the adjacent surfaces of the vertical walls of the vessel 1.

' In the modified form of the invention shown in Fig. 5 the bearing bracket 36 of the outer vessel is located yoke 37 in which is mounted for vertical movement a rectangular stem 38. Beneath the yoke the stem supports a socket member 39 for receiving the upper extremity of the driven shaft 8 while "above the yoke the stem is provided with a stop 40. A spring 41 is interposed between the socket member and the yoke 37. From this construction it is stated that the yieldable socket a gear provided with a centrally bearing 39 Will accommodate itself to vertical movements of the vessel 2 which move ments may result when the machine is in operation. A cover 42 is adapted to close the upper ends of the inner and outer vessels and as illustrated said cover is provided with suitable clamps 43 which are adapted to be engaged with the outer vessel to hold the cover in closed position. v

I claim l. A dish washer comprising an outer vessel having a substantially inverted conical bottom, an inner vessel revolubly mounted in the outer vessel and provided with lower rollers adapted to travel over the bottom of the outer vessel, lateral side rollers carried by the inner vessel and adapted to travel over the adjacent walls of the outer vessel, and means for revolving the inner vessel.
